问答题
[听力原文] UFOs There are many explanations for why UFOs visit the Earth. The most popular one is that they may be visitors from other planets. To fly such aircraft, their builders must develop different forms of aviation, because they seem to fly much faster than normal aircraft. The UFOs, it is believed, must contain scientists from other planets who are studying life on earth. It is even believed that several such aircrafts may have landed on earth and file space visitors may be living amongst us. But there are also less fantastic explanations available. Although some sightings of UFOs are-difficult to explain, most can be explained quite easily. In many cases the observers might have made a mistake. They might have seen a weather balloon or an aircraft. Or the light they saw in the sky might have been light from the ground, reflected onto the clouds. However, the exact cause of many sightings still remained a mystery. [难点解析]本文的难点主要是表示推测的几个句子。第一段最后一句中several such aircraft may have landed on earth和第二段第三，四、五句中的might have ＋V-ed可能会给听写造成困难，因为表示对过去的推测时have都轻读，[h)的读音省略，与前边的情态动词连读。如果不熟悉这一语音现象，错误很可能就会发生。补救的措施仍然是进行快速的语法分析。
